To c?? who-m 'it may concern Be n lq own that EDWARD P. SHELDON. a citizen :it the United Sto-tes, residing et New York, countv of Kings, and Stateof New York, have invented certain new and useful improvements in Stapling Mecha nisms. inllv describen and represented in the following speciticction and the accompanying drawings., forming s port. of the seme.

'l' his invention relates to certain improvements in stcpling mechanisms.

Stepling mechanisms are now employed in connection with printing machines. such, gior instance, as rapidly opei'etino machines for printnlg are 'formedcnd inserted into the wel) while it is in motion, or, es it is usually termed, on the run. been more 'usually' employed in connection with printing and folding mechanisms which operaie in connection with the web in which the columns of the printed matter ere arranged on the weh at right angles to its general direction or" trai/chend in the usual form oi such mechanisms the wire trom which the staples are formed is ed to o. stepling mechanism, or series of such mechanisms, mounted on s rotary carrier, the direction ci the wire feed being parallel to the axis of the rotary carrier. Such stepling mechanisms have also heen used, though to n more limited extent, in connection with print and folding mechanisms wi h operate in connection with running in which the coiumns of printed metter are disposed the 'web parallel to its direction of movement: Such mechanisms have also employed rotinrj.Y carrier in which the staple forming and inserting mechanisms are mounted, such mechanisms being erranged around the carrier so that the wire is ted to the carrier in the direction of its rotation instead ci parallel to its axis, es in the other class ot machines referred to.

The present invention has sp cial reference to the latter class of' stnpling meciianismsthough certain ot its tentures are capoble of use in connection with stcpling mechanisms of either clss.

The object of the in vention is to produce on improved stcpling mechanism which can he economically' constructed, and which shall he certain in its oper tionn the improvement newspapers, in which the staplesl lliese st-pling mechanisms have extending to certain 'details or" construction which `will hereinafter appear.

With this and other objects in viewfthe invention consists in certain-constructions, and in certain parts, improvements and comhinations es will be hereinafter; fully cle-v scrihed and then specifically pointed outin the clcinishereunto appended.

Figs. i7' to '20 inclusive are diagrammatic views illustrating the successive steps in the operation oifthe stc- .ple forming and inserting mechanism.

Referring to the accompanying drawings which illustrate one embodiment ci the. in vent-ion, the wire is derived from any suitable source osupply9 es,.:?or instance., from Vcaiimitated to forward varying lengths; of

nire in mcordance with the demands ot' the staple forming nicchamem. llhile the parrioular conetruction ot the wire toed may be varied, as shown, (sec Figs. 1 and il) there provided a driving sha/tt L) having; a gear which is driven through an intermediate 4l: from a gear on the main ehat't G ot the stapling mechanism. ln the machine illustrated, the shaft is provided with a plurality of' feeding; surfaces, said sur aces being so constructed as to draw varying amounts of wire from the source of supply. :in the particular construction illustrated, these rotary feeding surfaces consist of wheels. three such wheels, 7, 8 and 9, being employed and being;r tast on the shaft. These ivhcels are of varying dian'ieters, but since the;7 are on the Same shaft are given the saine number of revolutions per unit ot time, so that they have Varying Sur'tace speeds. A coperating feeding member, in

l the machine illustrated, is employed in Contitl! liti operating locking nection with these feeding surfaces, the -t'eeding member shown consistingof a, wheel 10 which is so arranged that it may cooperate with any of the Wheels 7, 8, 9. In the particular construction illustrated, the wheels 7, t5, 9 are provided with gears 11,.,12 and 123, these gears havingl ditlerent numhere oit teeth corresponding to the diitleront diametere of the wheels, and the wheel 10 is provided with a gear 14 Whioli may be caused to mesh with any7 of the gears 11, .12, 1B, :may he desired.

The conetruetion by which the wheel '10, when the saine is employed, is mounted, so that. it rnav cooperate ivith any ot' the other Wheels may be ividcliT varied. illustrated, the wheel 10 is supported. on stud l carried 'by an arm 16 projecting from a hub 17. this huh heine' sinoported by a long pin or spindle 18. This long pin or spindle 18- is carried h v a bracket 1) which .Forms a part of the machine trame. The hub 1T has, in 'the particular eom-truction Shown, extending troni it .an arm 2t) v-Jhifh arm einployed, in the ctmstruclion illustrated. tor Supl'iorting a locking' mcrhanism which may.

'lormod on the end ol the arm 20. This pin is sfurrouuded b v a, spring E28 which urges the pin forward. The coinomher `with which the pin engages ma) consist, as shown, ot a eteploed hloclr'i, his block being;f Secured entrees to the Yframe and having three eoclete, 25, 2li, 117, of dill'erent depth, with any one oi which thc pin may he caused to engage. ln the particular Construction shown, the Wheel is shown as coperatie with thc wheel l and the point olf the pin. is in engagement with the socket. Q5. Should i'olieJ desired to increase the toed of the vri the pin will be disengaged :trom the sorla'et 25 and the huh 1T will be slid along on the long pin 1B until the gear 14 meshes with the 12, at which time the pin 2l will be in position to engage with the Socket QG. The spring 23 noty only holds the pin in its socket, but also tends to rock thc hub 17 and throw` the wheel l0 against. the wheel with which it Cooperates. It' desired,a stop may he einployed to control the bito of the wheels on the ivire. this stop, in the construction illustrated, consisting oi a screw QS passing through a projection 22) extending; from the hub 1T. this screw bearing` against a block 30 tast on the tramo. ln order to preeent the ivire accurately to the bite ol the rolls,

' the arm 1G may be provided with a channeled guide block 31 through which the wire is led and which delivers the Wire to the Wheels.

Alter leaving the feeding mechanism h v ivhieh it d avvn from its source of supply, thil ivire is led to a wire presenting device whichniav bc variously eonstruotcd and lo cated. The wire pref-'mitingrl device and the icefliugr inccrha'uism will he so located with respect lo each other ae to leave a space iiiA which a slaelt supply of wire is tori'ned. Snell a Slack supply oi wire is iuditaited in Fig. El Where thc Wi-rc is shown in advance of the feeding mechanism as disposed in a loop. lv arrangin l the devices referred lo so as to provide :tor this loop, the necessity for absolute ccuraov in the action of the feeding mechanism is avoided. ltis ditlicult to so adjust the feeding;v devices as to, under all circumstances, have tho-m 'lood thel precise length oi iriro which is necessari 'for the formation ot the Staple, and in cae-e the supply should be insul'tlcient. the devices `which advanci` the wire for the Staple length would have imi'iosod upon them either the dirtir ot drawing' the wire throunl the wire leerlinginechanisn'i. which is undesirable, or, it might happen that the ivirc would be pulled out ol the wire advancing devices.

Melrose Y convenienti mounted on the'l block 49 for the stapleicrmer. fis shown (seeddig. 13) thekniie, marked 85,1s pivoted" in a recess 856 in the block by means o'a screw 87, this l knife poperating with a fixed knife S8 also carried in the block. l This imite may, as shown, be directly operated bya slide 89 Working in, an opening which is formed partly in the upper corner of the block and partly in e plate 90- secured to the side of the block., ln order to limit the movement of this slide, itA may be provided with a pin, as 91, Working in a recess 92 in thevplate 90 in order to eect a movement or the knife ift a direction opposite to that produced by the slide, there may be provided a spring rod construction 93 of ordinary type which construction may be con- .venientlylocated in a box 941 secured tothe front of the block 49. This box may also serve to assistin holding the knife 88 in position.

-The knife operating means should be of such a character as to enable the operation of the knife to be prevented during the revolutions of the carrier L12 when the Wire is not-taken by the staple former. Vhile the construction by which this is effected may be varied, as shown, the operation of the knife is effected through the cooperation of the slide 89 before described With a cam 95 which may be moved so as to be in or out of the path of the end of the slide. ln

the particular construction illustrated (sed Figs. 3, 10 and 11) the cam 95de arran'edr to slide in an opening in the frame, the sidijiig movement -being effected by means off a shouldered bar 96 arranged to Work through an opening in the cam. The bar is provided With two shoulders 97, 98 and the cam is provided with corresponding shoulders `99, 100, the shoulders being suitably beveled,l

I 100, move the cam from the position shown in Fig. 11 to the position shown in Fig. 1()v lt is desirable that the operation by which the cutter is rendered inoperative take place simultaneously with the operation ci." the controller which renders the staple forming jaws inoperative to seize the Wire. The cutter operating devices so far described lend themselves readily to eiiect this result, though other suitable operating mechanisms may be employed, if desired. Thev operating connections by which the sliding bar 96 is moved when desired may be considerably varied, but, in the machine Shovvm'the end of the bar is pivoted to one of the arms 101 of a bell-crank lOl-102 pivoted at 103 on the frame of the machine. The arm 192 of this bell-crank is connected by a rod 104 to an arm 105 (see Figs. 3, 10 and 11)! on the shaft 74 before referred to. lVhen, therefore, the shaft 74C is rocked to interpose the 'controller in the path ot the jawiactuator, the knife operating cani is slid back and the /cutting operation is intermitted, it being understood, of course, thatthe spring rod construction 93 normally holds the knife 85 away from its coperating knife so that the Wire may pass freely between these knives.

.From the operations so far described, it will be understood that as the carrier 42 rotates, the staple forming jaws will be successively brought into the position illustrated in Fig. 17 and will, when permitted to do so, by the controller, seize the Wire and advance it the necessary distance to pull forforward a length suilicient to form a staple,

after which the cutting mechanism operates to separate this Wire length from the Wire.

Although the devices for controlling the Wire, including the devices for preventing the backi`eed are so constructed as to permit thel Wire to be freely advanced by the action of the staple former, it may be desirable to prevent the Wire from -slipping back' through the jaws, should, for any reason undue strain beV placed upon it. While this say be 'effected in various Ways, in the mac ine illust-rated, it is effected by causing the staple former, after it has seized the Wire, to retreat slightly into its socket, so as to bend the Wire slightly, as illustrated in Fig. 18. This retreating operation takes place just after the former jaws have gripped the Wire and it bends. the Wire across the shoulder of the socketso that the Wire is clamped between the grippingjaws andthe edge of the socket and the entire strain of forwarding the Wire is not resisted by the grip of the gaws. i

After the cutting devices have operated, the position of the parts'justlafter the out; ting operation has taken piace being illustrated in Fig. 18,-the forming jaws retreat still further-into their socket, so as to bend up the ends of the Wire to form the staple legs, this being eected by the arm 62, the shaft 60 and the parte immediately connec'ted therewith, including thecam 56. 4 rlhe position ot the parts When the staple isy fully tended to produce a collected product, may t iso Well be the collecting,r cylinder of the printing machine. ln the particular machine shoivn, the second rotary carrier, marked 1,06, is intended to be used as a collecting' cylinder, although the devices for retaining ,the sheets thereon are not shown, inasmuch as they have no bearing on the present invention. The second rotary carrier referred to Will,`in the best constructions, be provided with devices which operate to clench the staple, which devices may be varied widely in construction. ln the particular' machine shown, these clenching devices include a clenchcr which as shown comprises a pair of members 107 pivoted in a block 108 (sce Figs. 9 and 15). It will he understood, of course, that Where there are a plu rality of staple driving mechanisms employed, there will loe a plurality of cleuchers.

ln the particular.` machine illustrated, ter a staple has been .formed7 as hei-einbefore described, it is, by the continued rotation of the ari-ier 42, brought around to the insert-ing point and is then thrustl through the paper, this being effected by giving the staple former a quick movement in its socket toward the circumferemrc of the carrier, this quick movement causing the legs of the staple to penetrate the paper. At the time the legs of the staple penetrate 4the paper, they a re opposite the clenching meinbers 1u?, the position of the parts at this time 'being substantially that shovvn in Fig. 9. The clenchingmemhcrs are then operated so as to bend down the staple legs, the position of the parts at the close of this operation being well shown in Fig. 20.

.lt obvious that as soon the staple is driven and clenched, the holding jaws of the staple former should be opened to release it. While this may be accomplished in various Ways, in the particular machine shown, this releasing operation is cllected by a cam 10S) (sco Fig. 1l) which is located in the patn of thractualor pin (S5 so that this pin strikes and rides up on it, thus opening the jaws and releasing' the staple.

'.lllc means for operating the clenching members 10T may be varied within wide limits, but in the best mmstructions Will include a driver the construction of which may be varied. ln the particular machine illustrated (sce Fia'. 9) the driver consists of a` plunqer 110, it being understood that. in the form of mechanism employed there 'will be one of these plungers for cach pair of clenching members. While the particular construction of the operating' means for the drivers may be varied, it will include actuating mechanism which, in part, at least, lies outside the carrier. ln thc particular machine shown', there is provided a series of actuator or strilou'arms lll, each of these arms being mounted on a rock-shaft 112 whichV rock-shafts are mounted in and noe/toas extend through onel of the heads of the cylinder. These rock shaf 112 at their outer ends have secured to them cranlearms 113. These arms are provided with pins 114 (see Fig. .15) which pins carry rolls 115. These rolls run onA a track 11G formed in a stationi ary plate 11G secured to the frame by holte, or in any other suitable manner. This track may., as shown, be generally circular in. outline, but is cut away in order that the shafts 112Viuay be rocked at the staple clenching point to produce a movement of the elena-hers.

The machines in which this invention will he emhodicd will, as a rule, he liiglspecd machines, and, therefore provision should be made for quickly effecting the clenching operation, there being but a very limited time. allowed for this operation. `While this may he accomplished in various Ways, it may be effected by providing a governing device which controls the action of the shaft and the 'actuating parts connected there-v with. ln the particular machine shown, this governing device consists of a. governor block 117 which may be adjustably connected to the track. lu the construction illustrated, the track near the staple clenching` point is provided with a slot 118 which is engaged hy a projection 119 on the block. rlhis projection 119 is or may be provided with a tapped hole which is engaged by a long screwl20, this screnT passing through an opening 121 in the frame and having' a4 collar 122 thereon. By this construction the end of the governor block maybe adjusted toward or away from the staple clenching point. Then a governor block like that described is employed, the pins 114i carrying the cam rolls 115 may he provided Figs. 4 and 5) with bearing; blocks 123, these blocks being located just inside theI cam rolls. These blocks should have, as shown, square faces for coperatingwith the governor block. It will be understood that by the construction just described, ,when the bearing blocks on the crank arms reach the end of the governor block they may drop quickly oft' the end so as to produce a quick movement ofthe shafts, Whereas, if the movement of the shafts depended on the passing ofi' of a roll or similar curved surface from the end of the track, the movement would be slower and more or less uncertain on account of the curved surface of the roll.
